Both planes and rockets have the same problems: control system failure,
pilot error, mechanical fault can all lead to loss of control, which
tends to mean plummeting from the sky (or with rockets, exploding). They
also tend to have everything under software control (albeit multiple
systems).

There's no failsafe for those



Nuclear power plants have hard-wired, mechanical or passive safety
systems, that continue to work, even if the control systems go wrong or
operators do things that they should not (similar would be too bulky and
heavy for aircraft).

There is for power stations, and railways ...


I rather think that those were the points that I was making -
particularly as I also mentioned the effect of gravity when things go wrong.
